MF3DH4200DA4/01J

Application Specific Microcontrollers Overview

The MF3DH4200DA4/01J is a MIFARE DESFire EV2 contactless multi-application IC from NXP Semiconductors. It features 4 kbit EEPROM and operates at 13.56 MHz compliant with ISO/IEC 14443A. The device supports data transfer rates up to 848 kbit/s and includes hardware cryptographic engines for AES-128 and 3DES. It holds Common Criteria EAL5+ certification and utilizes a MOA4 plastic leadless module carrier package (SOT500-2) with a high input capacitance of 70 pF.

Application Specific Microcontrollers Feature Summary

• Common Criteria EAL5+ certified security with AES-128 and 3DES hardware engines
• 4 kbit non-volatile memory with transaction-oriented anti-tear mechanism
• Supports up to 848 kbit/s data transfer rates over ISO/IEC 14443A interface
• MOA4 package (SOT500-2) optimized for small form factors with 70 pF input capacitance

Application Specific Microcontrollers Applications

• Secure public transport ticketing
• Multi-application smart city and mobility cards
• Secure access management systems
• Micro-payment and loyalty programs

Application Specific Microcontrollers Procurement Notes

Verify component authenticity through authorized distribution channels due to the presence of Originality Check features. Confirm package integrity as the device is supplied in a plastic leadless module carrier. Ensure design compatibility with the specified 70 pF input capacitance requirements for the MOA4 package configuration.

Application Specific Microcontrollers Selection Notes

Select this variant specifically when a 70 pF input capacitance is required for compact antenna designs, distinguishing it from the standard 17 pF MF3Dx2 series. The 4 kbit memory capacity suits applications requiring moderate data storage without excessive cost. Verify that the MOA4 package dimensions fit the target PCB layout constraints.

Application Specific Microcontrollers Part Context

This part belongs to the MF3D(H)x2 family, representing the third generation of MIFARE DESFire products. It succeeds the DESFire EV1 and D40 models, offering backward compatibility while introducing advanced features like Virtual Card Architecture and Transaction MAC. The 'H' designation indicates the high input capacitance variant suitable for miniaturized card forms.

Application Specific Microcontrollers Replacement Considerations

Functionally compatible replacements within the same family include MF3D4200DA4/01J (standard 17 pF capacitance). For higher memory capacities, consider the MF3DH8200DA4/01J (8 kbit) or MF3DH9200DA4/01J (16 kbit), provided the application logic supports the increased storage and any associated pinout similarities are verified.
